During an 18 month period, preterm infants of 34 weeks’ gestation or less were prospectively examined for periventricular leucomalacia (PVL) by cerebral. Periventricular leucomalacia is the term used to describe cerebral infarctions occurring near the lateral ventricles in neonates. The lesion was first described by.

Risk factors in the development of intraventricular haemorrhage in the preterm neonate. Although no treatments have been approved for use in human PVL patients, a significant amount of research is occurring periventricylar developing treatments for protection of the nervous system.
Periventricular leucomalacia and neurodevelopmental outcome in preterm infants.
On ultrasound, hyperechoic areas are firstly identified in a distinctive fashion in the periventricular area, more often at the peritrigonal area and in an area anterior and lateral perventricular the frontal horns periventricular lucomalacia matter should be less echogenic than the choroid plexus. Log in Sign up. Some of the most frequent signs include delayed motor development, vision deficits, apneaslow heart ratesand seizures. National Institutes of Health Web Site.
Other ongoing clinical studies are aimed at the prevention and treatment of PVL: This article has been cited by other articles in PMC.
It is important to note that both periventricular and subcortical leukomalacia correspond to a continuous disease spectrum. Abstract During an 18 month period, preterm infants of 34 weeks’ gestation or less were prospectively examined for periventricular leucomalacia PVL by cerebral ultrasound. Those patients with severe white matter injury typically exhibit more periventrciular signs of brain damage. Correlation of ultrasound, clinical, and nuclear magnetic resonance functions.
D ICD – Progressive necrosis of the periventricular tissue with resulting enlargement of the ventricles is called end-stage PVL. Infants with severe PVL suffer from pegiventricular high levels of muscle tone and frequent seizures. However, the correction of these periventrivular occurs “in a predictable pattern” in healthy premature infants, and infants have vision comparable to full-term infants by 36 to 40 weeks after conception. The New England Journal of Medicine.
Since the original description by Virchow inmuch progress has been made in establishing the underlying cause of this condition. Intrauterine hypoxia Infant respiratory distress syndrome Transient tachypnea of the newborn Meconium aspiration syndrome pleural disease Pneumothorax Pneumomediastinum Wilson—Mikity syndrome Bronchopulmonary dysplasia.
Despite the varying grades of PVL and cerebral palsy, affected infants typically begin to exhibit signs of cerebral palsy in a predictable manner. As previously noted, there are often few signs of white matter injury in newborns.
An emphasis on prenatal health and regular medical examinations of the mother can also notably decrease the risk of PVL. Because neural structures are still developing and connections are still being formed at birth, many medications that are successful for treatment and protection in the adult central nervous system CNS are ineffective in infants. However, since healthy newborns especially premature infants can perform very few specific motor tasks, early deficits are very difficult to identify.
A damaged BBB can contribute to even greater levels of hypoxia. In an Israel-based perlventricular of infants born between andseizures occurred in ofor The processes affecting neurons also cause damage to glial cells, leaving nearby neurons with little or no support system.
Alternatively, damage to the BBB can occur due to maternal infection during fetal development, fetal infections, or infection of the newly delivered infant.
Pneumopericardium Persistent fetal circulation. Robbin’s Review of Pathology.
Current clinical research ranges from studies aimed at understanding the progression and pathology of PVL to developing protocols for the prevention of PVL development.
Images in this article Fig. Another common but severe outcome of PVL patients is the development of epilepsy.

The white matter necrosis often occurs in a characteristic distribution with the pattern being dorsal and lateral to the lateral ventricles and with involvement of the centrum semiovale, the optic trigone and occipital horns and acoustic temporal horn radiations. The prognosis of patients with PVL is dependent on the severity and extent of white matter lecuomalacia.
